Turner Broadcasting System Inc. on Monday promoted David Levy to president to oversee channels including TBS and TNT. He had been president of sales, distribution and sports for Turner.

The promotion comes a few weeks after Time Warner Chief Executive Jeff Bewkes picked John Martin as Turner's new chief executive when current CEO Phil Kent steps down in 2014. Levy had been a potential candidate for that post.

Levy will oversee domestic entertainment, animation and young-adults networks and business portfolios for the cable unit as well as continuing to oversee sports and advertising. In addition to TBS and TNT, Levy will be in charge of the company's Turner Classic Movies, TruTV, Cartoon Network, Boomerang and Adult Swim.

The new role for Levy will essentially add a layer to Turner management once Martin takes over. Interestingly, while Turner and Kent are based in Atlanta, Martin and Levy are New York-based. The appointment of Martin has some speculating that Turner's Atlanta operation may shrink in the coming years as more key executives are located elsewhere.
